Mineralys Therapeutics Presents Late-Breaking Data on Lorundrostat and Heart Failure Risk Biomarkers at The Endocrine Society Annual Meeting (ENDO 2026)
Rhea-AI Summary
Mineralys Therapeutics (Nasdaq: MLYS) presented late-breaking data at ENDO 2026 on lorundrostat’s effects on heart failure (HF) risk biomarkers in uncontrolled hypertension. A post hoc proteomic analysis of 1,004 participants from the Launch-HTN and Advance-HTN trials showed significant changes in RAAS-related and HF risk biomarkers.
Lorundrostat was associated with increased renin, decreased angiotensinogen, and reductions in 6 of 11 candidate causal HF biomarkers, including NT-proBNP. Coordinated shifts in fibrosis, hemostasis and protease inhibitor markers support further evaluation of lorundrostat’s therapeutic potential in HF. Lorundrostat is under FDA review with a PDUFA target date of December 22, 2026.

– Lorundrostat was associated with significant reductions in heart failure risk biomarkers in a proteomic analysis of data from participants with uncontrolled hypertension –
– Coordinated reductions in biomarkers of fibrosis and heart failure suggest lorundrostat may favorably modulate the physiological processes that drive heart failure –
RADNOR, Pa., June 14, 2026 (GLOBE NEWSWIRE) -- Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a biopharmaceutical company focused on developing medicines to target hypertension and aldosterone-related adverse outcomes in comorbid conditions such as chronic kidney disease (CKD), obstructive sleep apnea (OSA) and other diseases driven by dysregulated aldosterone, today presented new data on the effect of lorundrostat on heart failure (HF) risk biomarkers. This post hoc analysis of circulating proteomic data from participants enrolled in the Company’s Launch-HTN and Advance-HTN trials was presented in a late-breaking poster presentation at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Illinois.
“People with uncontrolled hypertension are at particular risk of heart failure, a condition where more effective treatments are still neededi,” said Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “Aldosterone plays a well-established roleii in driving this disease, and these findings suggest that lorundrostat may act on the biological processes that contribute to heart failure, supporting further evaluation of its therapeutic potential in this setting.”
This analysis characterized the systemic pharmacodynamic (PD) effects of lorundrostat and generated hypotheses regarding its potential modulation of pathways implicated in HF pathophysiology by profiling circulating protein biomarkers at baseline and after 12 weeks from 1,004 participants enrolled in the pivotal Phase 3 Launch-HTN and Phase 2b Advance-HTN trials.
The PD analysis confirmed that lorundrostat was associated with significant increases in renin and decreases in angiotensinogen, reflecting target engagement of the renin-angiotensin-aldosterone system (RAAS). Lorundrostat was associated with significant reductions in 6 of 11 recently published candidate causal risk biomarkers of incident HF, including NT-proBNP, consistent with the hypothesis that RAAS inhibition favorably modulates processes involved in HF risk.iii
Compared to placebo, lorundrostat treatment led to coordinated changes in key biomarkers: reductions in markers of scarring and heart failure risk and increases in markers of hemostasis and protease inhibitor activity. These changes occurred together, suggesting a broad, consistent effect on disease pathways—particularly reducing harmful fibrosis—rather than isolated, random shifts.
These results provide biological plausibility and support further evaluation of the therapeutic potential of lorundrostat in heart failure.
Lorundrostat is currently under review by the U.S. Food and Drug Administration, with a Prescription Drug User Fee Act (PDUFA) target date of December 22, 2026.
About Launch-HTN
The Launch-HTN trial (NCT06153693) was a global, randomized, Phase 3 double-blind, placebo-controlled clinical trial of adults whose blood pressure remained uncontrolled despite being on two to five antihypertensive medications. Participants were assigned to one of three groups: lorundrostat 50 mg once daily; lorundrostat 50 mg once daily with the option to increase to 100 mg at week six based on prespecified criteria; or placebo. The primary endpoint was change from baseline in systolic blood pressure at six weeks versus placebo, measured by automated office blood pressure monitoring.
About Advance-HTN
The Advance-HTN trial (NCT05769608) was a randomized, Phase 2 double-blind, placebo-controlled clinical trial that evaluated the efficacy and safety of lorundrostat for the treatment of uncontrolled hypertension or resistant hypertension, when used as an add-on therapy to a standardized background treatment of two or three antihypertensive medications in adult participants. Participants who met screening criteria had their existing hypertension medications discontinued and started on a standard regimen of an angiotensin II receptor blocker (ARB) and a diuretic, if previously on two medications, or a standard regimen of ARB, diuretic and calcium channel blocker if previously on three to five medications. Participants who remained hypertensive despite the standardized regimen were then randomized into three cohorts and treated for 12 weeks: lorundrostat 50 mg once-daily; lorundrostat 50 mg once-daily with the option to increase to 100 mg once-daily at week four based on prespecified criteria; or placebo. The primary endpoint was the change in 24-hour ambulatory systolic blood pressure at week 12 from baseline for active cohorts versus placebo.
About Hypertension
Having sustained, elevated blood pressure (BP) (or hypertension) increases the risk of heart disease, heart attack and stroke, which are leading causes of death in the United States. In 2022, more than 685,000 deaths in the United States included hypertension as a primary or contributing cause. Hypertension and related health issues resulted in an estimated annual economic burden of about
